Keeper, who plays Ben’s sister Louise, will also be making her exit from the show.
Following the “death” of her fiancé Keanu, she has been struggling to cope with what her and her family did as well as looking after newborn daughter.
There are 7/1 odds on her being killed but fans have also speculated she might leave with her mum Lisa Fowler (Lucy Benjamin) to move to Portugal.
Talking to The Sun, Keeper said: ”I have loved playing Louise Mitchell over these past few years, and I feel honoured to have been part of such an iconic show.
“Working with our incredible cast and crew has been a joy and I shall miss my EastEnders family greatly.”
Eastenders continues tonight, Monday, January 20, on BBC.
